United are expected to be among the busiest clubs in the market before the transfer window shuts at 11pm on Monday.

But Van Gaal will play a very limited role in the comings and goings at the club's training ground in Carrington. Instead, it will be the club's executive vice-chairman who will be negotiating any deals.

"Ed Woodward is doing the transfer market so I don't interfere in that process," the United manager said.

"I am not the one who can choose.

"I am the sportive side, he is in the buying and selling side."

Van Gaal expects to have a new-look squad available to him on Tuesday once all the deals have been completed.

The former Holland coach revealed on Thursday that he has informed those players who he feels are surplus to requirements.

Van Gaal will not force those on the periphery out of the club if they do not want to go, though.

"I gave my opinion and the player can do what he wants with that opinion," he said.

Up to 11 players could depart Old Trafford, chief among them Tom Cleverley, Danny Welbeck, Shinji Kagawa and Javier Hernandez.

Cleverley captained United in their second pre-season tour game, but he had a wretched match against Sunderland last weekend.

The midfielder is in talks with Aston Villa over a potential £8million move while Valencia are also said to be interested in the England international.

United are thought to be reluctant to sell Welbeck to a rival English club, while Kagawa and Hernandez have been linked with Borussia Dortmund and Juventus respectively.

Allowing Welbeck to leave has surprised some United fans, but Van Gaal says he has given his players enough time to persuade him they should stay.

"Before I started I said that I shall give every player a fair chance and I have done that," he said.

"We are building up a new team."

United hope to sign at least one new player before the window shuts.

Daley Blind is on Van Gaal's wanted list, but Ajax hope to keep hold of the versatile midfielder for another year.

United have privately distanced themselves from reports linking them with moves for Arturo Vidal, William Carvalho and Nigel de Jong.

The Old Trafford club do still have plenty of money to spend though despite the record £59.7million signing of Angel di Maria on Tuesday, and it would be a shock if there were no new arrivals before the deadline.

The transfer of Di Maria took United's total summer expenditure to over £130million following the signings of Luke Shaw, Ander Herrera and Marcos Rojo.
